The thing i've missed really is that in csync DB the 'source' FQDN
addess is saved, so when i've switche IP/FQDN, newer files get 'marked'
with new FQDN, that clearly does not work with older FQDN.

Yesterday i've done:

	update dirty set myname='hermione.sv.lnf.it' where myname='gaio.vpn.sv.lnf.it';

and csync come back working as usual on the 'old' IP.


Seems to me that really it is hard to work with csync2 with multiple
IP... because i use it mostly to distribute some configuration files,
probably it is better to switch to some other tool, eg RCS, so git.


Thanks.
